To represent the opposite of this number, if it is positive nineteen,
he would need to first take nineteen steps back to reach his original
position which in this case represents zero. He would then need to take
another nineteen steps backwards, to reach negative nineteen.

Answer:Rate of change is 7
Option B is correct.
Step-by-step explanation:
We need to find the average rate of change for 
from x = 4 to x = 6
The formula used to find average rate of change is:
Where b = 6 and x = 4
Finding f(6):
Finding f(4):
Now Putting values:
So, Rate of change is 7
Option B is correct.

Answer:
61.25 M
Step-by-step explanation:
the question is trying to mislead you with the blue amount, you are only looking for the amount of white needed.
this means you multiply 1.75 (1 3/4) times 35 sets, getting you 61.25 M
Answer:
Step-by-step explanation:
In the two independent samples application, it involves the test of hypothesis that is the difference in population means, μ1 - μ2. The null hypothesis is always that there is no difference between groups with respect to means.
Null hypothesis: ∪₁ = ∪₂. where ∪₁ represent the mean of sample 1 and ∪₂ represent the mean of sample 2.
A researcher can hypothesize that the first mean is larger than the second (H1: μ1 > μ2 ), that the first mean is smaller than the second (H1: μ1 < μ2 ), or that the means are different (H1: μ1 ≠ μ2 ). These ae the alternative hypothesis.
Thus for the z test:
if n₁ > 30 and n₂ > 30
z = X₁ - X₂ / {Sp[√(1/n₁ + 1/n₂)]}
where Sp is √{ [(n₁-1)s₁² + (n₂-1)s₂²] / (n₁+n₂-2)}
Try to find the common factor which is 2.
So:
Multiply by 2 both variables in parenthesis and you get:
2*(l+w)
